NIkon 7900 SD card problems

That is what you get when the camera memory has no images. And the SD card is missing. This does not seem to be a problem. The tool menu will let you format a new SD card.

Are you using a Micro SD to SD adapter?

No. The 7900 uses only SD cards, not SDHC cards.

Having gone five months without a response, I assume my suggestion to use a card reader solved the problem.

Sounds like you didn't use the "safely remove hardware" function when you removed the card from the computer.

Try jiggling the lens. Use compressed air to blow out any grit around the lens barrel. If that doesn't do it, you'll need to get the camera serviced.

Unfortunately the Nikon Coolpix 7900 does not have a 'display' button to take care of this. So you need to go through Menu to access Setup menu. Here you will get option to customize the display.

You may know this already, but you don't need the camera to upload photos. I have used Nikon Digital SLRs for several years and have never uploaded from the camera. You should be able to do so, but in the mean time, remove the SD card and use a SD card reader. If your PC doesnt have a built in SD reader, get a USB version like the SanDisk MicroMate or get SD with a built-in USB plug(see attached photos for both. When connected to your PC, either will show up as a removeable drive on your PC from which you can copy the files onto your PC's harddrive: save the photos, back them up, then use the camera to format the SD card--this is the best way to clear/erase the card. Then try opening the photos with the Nikon software or photoshop or if they are jpegs, windows will view them. Using the camera to upload photos, in my opinion, should only be done when you do not have a way to read the SD card. This can be the begining of a productive workflow and part of the process for organizing and backing up photographs. You should also watch the Nikon website for software updates to fix bugs: http://support.nikontech.com/app/answers/detail/a_id/61 You should also check for firmware updates for your camera(1.11 is the latest for the D40 and no updates yet on the D40x): http://support.nikontech.com/app/answers/detail/a_id/13783

sd hc cards are not supported by 7900, you will never can use such a 4gb card with this camera

hello

are you using a removable SD memory card?

check to see if your card is compatible with your camera.

the card maybe corrupt or may need formatting, try that after you back your pictures, movies up.

if the SD card was bought on auction site, may be a counterfeit. (the legit cards have serial numbers on them)
